fc | R Documentation |
A community-level measure of ecological niche complementarity measured as the total branch length of a functional dendrogram based on qualitative differences in visitor assemblages between plants.
fc(web, dist="euclidean", method="average", weighted=TRUE)
web |
A bipartite interaction web, i.e.~a matrix with higher (cols) and lower (rows) trophic levels. |
dist |
A distance accepted by the function |
method |
The linkage method to be used by |
weighted |
Option to analyse the web as binary or as weighted network. Default is weighted=TRUE, but analysis presented in Devoto et al. (2012) uses weighted=FALSE. |
